| - 9 - The road springs have given no trouble in respect of any fractures of the leaves, from an outside view. The lubrication appears to have been satisfactory. There has been no squeaks developed. The riding and road holding qualities of the car requires more damping for high speeds and less damping for town work. The passengers in the rear seats are thrown too easily when going over ridges. The front of the car rides heavy at low speeds, but is good for medium and high speeds. The jacking pads fitted on the rear springs make it less difficult to jack the car up on the road. HYDRAULIC DAMPERS LOP.FB.26S.LEC.331. These have been free from mechanical knocks, loss of oil negligeable, an average of 8 cc's of oil has been added to each damper during the mileage. There has been no trouble with any one damper becoming loose on the frame. The loading has remained consistant, considerable slackness has developed endways in the bearings of the controlled damper arm BRACKETS attached to the axle. The aera of the bearings do not appear large enough to take care of the thrust. The connecting links of the rear dampers have given no trouble, lubrication of the ball ends has been ample. ELECTRICAL EQUIPMENT DYNAMO The output has been satisfactory. Examination of the brush gear and comutator show slight burning and flats forming on the leading edges of the segment of the comutator. The brushes are free in the guides. There is very little carbon dust. STARTER MOTOR R.R. SCHEMES 399-417 At no time have we had any difficulty in starting. The motor has turned the engine vigourously when cold (garage temp. approx. 5°C) The starter teeth and flywheel teeth showed no damage due to crashing. | ||
